Pros:
The fact that this course exists is a plus, Japan doesn't seem to have many. I'm really not qualified to write a review for this course since I was only able to play the back nine, but since there were no other reviews; I thought I might as well. The holes I did play were fairly easy; not too long and fairly open. I think I pared almost every hole. It would be hard to lose a disc here (although the front nine did appear to have water hazard(s).
Cons:
This course is in a multi use park, when I played, non-playing pedestrians were a major issue. The front nine was completely occupied as a staging area for a running event that day which prevented play. I was disappointed there were no locals playing and no pro shop open, but this was probably due to the running event. Also, there was a large group of toddlers on some sort of nature walk, that were totally oblivious to our presence (invisible Gaijin). The thought of hitting a Japanese toddler with a disc was horrifying enough for us to wait patiently for them to clear the area
Other Thoughts:
After a 3-4 hour trip (from Sasebo city), when we showed our discs to the ticket seller (course is located in a 400Y fee park), we were told "Dame" with crossed arms which means "totally bad/no way". We went ahead and paid admission anyway since we had come so far just to check it out. Luckily we were able to play the back nine, but overall it was a disappointment. I would recommend (having someone who speaks Japanese) calling first before making a long journey to play this course.
